Six-Speed Manual Tremec T56 (MM6/M12) Car Transmission
"2003 Model Year Summary
• No changes are scheduled for the 2003 model year
LOW MAINTENANCE
The 6-speed uses DEXRON III fluid and is certified "fill-for-life," requiring no fluid changes. The clutch is activated hydraulically, which automatically compensates for clutch disc wear, eliminating manual adjustments. The 6-speed was originally designed to require virtually no maintenance.
OVERVIEW
The Tremec T56 evolved as a higher-torque capacity, six-speed version of the proven M49 five-speed manual transmission, and was introduced in the 1993 Chevrolet Camaro and Pontiac Firebird. It was also added to the all-new 1997 Corvette.
Last year the 6-speed received carbon blocker rings on its synchronizers, increasing the durability of the transmission. A new Z06 Corvette model was added for model year 2001, featuring a high output LS6 V8 engine. To get maximum performance from this model, a variation of the Tremec T56 (the basis for the MM6) with a higher ratio first gear was used (M12 - see specifications page).
Design features include a combination of double-cone and triple-cone synchronizers on all forward gears. Synchronizers act like clutches to speed up or slow down a gear that is being shifted to. Double-cone synchronizers have two friction surfaces to effect this gear acceleration, and triple-cone synchronizers have three friction surfaces. The greater the friction surface, the easier the transmission is to shift. In addition, double-cone and triple-cone synchronizers are smaller in diameter than a single-cone synchronizer with the same friction area allowing the transmission to remain more compact.
Further refinements in design include needle bearings on all forward gearsets and 5th and 6th gear synchronizers located on a countershaft. The countershaft location of the 5th and 6th gear synchronizers allow those gears to be selected without affecting the 1st through 4th gearsets, contributing to ease of shifting."
I belive it also has steel shift forks factory and carbon blocker rings. Transmission is still int he car right now.. has been sitting all winter. Will pull depending on interest obviously.

The only thing you will have to do is change the shift cup from a gto to the fbody one then the fbody shifter will bolt right up. They are like 30 dollars.
